Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

Assumption: Your SRX uses a top-post battery with a single hold-down bracket in the engine bay.

• 🔥 Keep sparks/flames away—battery gas can ignite.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Remove any battery cover or air ducting if it blocks access.
• If plastic push-clips are used, remove them with a trim clip remover.

Step 2: Disconnect the negative (-) cable

• Use a 10mm socket with a ratchet to loosen the negative terminal clamp nut/bolt.
• Twist the clamp gently and lift it off the negative battery post.
• Tuck the cable aside so it can’t spring back.

Step 3: Disconnect the positive (+) cable

• Flip up/remove the positive terminal cover (if equipped).
• Use a 10mm socket to loosen the positive terminal clamp nut/bolt.
• Remove the clamp from the positive post and keep it from touching metal parts.

Step 4: Remove the battery hold-down

• Locate the hold-down bracket at the base of the battery.
• Use a 13mm socket, ratchet, and 6" extension to remove the hold-down bolt(s).
• Lift out the hold-down bracket and set it aside.

Step 5: Remove the old battery

• Lift the battery straight up and out (it’s heavy—use good posture).
• If the clamps won’t release from the posts, use a battery terminal puller (specialty) (it presses the clamp off without prying).

Step 6: Clean and prep the connections

• Use a battery terminal cleaning brush (specialty) to clean corrosion from the inside of the cable clamps.
• Wipe the area with shop rags.
• Install battery terminal anti-corrosion pads on the posts (one on +, one on -).

Step 7: Install the new battery

• Place the new battery into the tray with the posts in the same orientation as the old one.
• Reinstall the hold-down bracket and start the bolt(s) by hand.
• Tighten with a 13mm socket, then Torque to 20 Nm (15 ft-lbs) using a torque wrench.

Step 8: Reconnect the positive (+) cable first

• Push the positive clamp fully down on the positive post.
• Tighten with a 10mm socket, then Torque to 17 Nm (13 ft-lbs) using a torque wrench.
• Reinstall the positive terminal cover (if equipped).

Step 9: Reconnect the negative (-) cable last

• Push the negative clamp fully down on the negative post.
• Tighten with a 10mm socket, then Torque to 17 Nm (13 ft-lbs) using a torque wrench.
• Lightly spray terminals with battery terminal protectant spray.

Step 10: Reinstall covers and any removed ducts

• Reinstall any battery cover/air ducting.
• If clips were removed, reinstall them by hand (don’t crush them with tools).

✅ After Repair

• 🔑 Start your SRX and confirm normal cranking (no slow start).
• 💡 Check for warning lights; some may take a short drive to clear.
• 🪟 Relearn power windows if needed: use the window switch to fully down, then fully up, holding the switch for 2-3 seconds at each end.
• ⏰ Reset clock and radio presets if they were lost.
• 🔍 Look for looseness: terminals should not rotate by hand.
